Miami: Two US astronauts began the 200th spacewalk at the International Space Station on Friday, following a brief delay after National Aeronautics and Space Administration (NASA) discovered a water leak in equipment that helps power their spacesuits. The official start time, 9:08 am (local time), was about two hours after it was supposed to begin, according to NASA. It was discovered as the astronauts were seated in the airlock inside the space station, before they ventured into the vacuum of space. The plan is for the astronauts to take turns using the SCU, and alternate using battery power in their suits. The box weighs 200 pounds (91 kilograms) on Earth, and routes data and commands to experiments inside the space station, Navias said.
